>Marta is a dual-pane file manager. Most of the time you work with two directory panes placed side-by-side. This allows you to do the basic file operations such as copying or moving files in a fast and efficient way, because you can see both source and target directories, and you can copy or move files directly, without copy-pasting it.

Just in case, it could be categorized as a OFM (Orthodox File Manager):

What started it all is the Norton Commander for DOS.

Thank you, though I knew most of those info as - unfortunately - I was there, in the sense that I was in my twenties when NC came out, I practically started my computing experience at work using NC and I couldn't imagine doing some tasks without a dual pane filemanager, and when the NC was killed by Symantec I mourned the loss (and quickly found some decent alternatives, the one with the most "NC feeling" being IMHO DN - Dos Navigator and later NDN - Necoromancer's Dos Navigator).

As a side note, what not everyone knows/noticed, 7-zip it is also a (almost orthodox) dual pane file manager, very handy to manage, besides files residing on mounted filesystems also those inside archives (obviously) and those inside disk/disc/drive images, such as .iso, .img and similar.

I think even it was preceded by the (wonderful) PFM file manager, which has a modern-day descendant in the Linux world.
